hey, I asked a question in your hair/make-up tips post, but it's on the next page now and I realized you might not see it. anyway, I had a question about the baking soda thing - do you add it to the bottle each time? (because it goes away so you just keep adding it) or do you take some out, mix it and then get in the shower to wash your hair? I try not to be too hard on my hair (rarely blow dry etc), but I do like to straighten my hair now and then and it's not very good for it so it's good to know some things I can do for it. thanks!
